Introduce option 'global_routes' for ejabberd_service

Browse Source 
The option emulates legacy behaviour which registers all routes
defined in `hosts` on a component connected. This behaviour
is considered harmful in the case when it's desired to multiplex
different components on the same port, so, to disable it,
set `global_routes` to `false`. The default value is `true`,
e.g. legacy behaviour is emulated: the only reason for this is
to maintain backward compatibility with existing deployments.
